Product Team · 2 specialists

You describe what you want. Your team makes it buildable.

Tell your Product Manager what you need in plain English. They read your actual codebase, draft a structured Product Requirement Document (PRD) grounded in your real architecture, and your Senior PM challenges it for gaps. By the time your Build Team starts, the spec is tight — and you haven't built the wrong thing.

How it works

Code-aware from the first draft.

Your PM reads your actual codebase before drafting — so the PRD references real architecture, not generic advice. Your Senior PM challenges it, and you review across multiple rounds. This is not one-shot generation.

Stage 1

Raw idea — you

Describe what you want in plain English. Two sentences is enough. You don't need to write requirements — that's your team's job.

Stage 2

Draft PRD — Product Manager

Your PM reads your actual codebase and drafts a structured, code-aware PRD that references your real services, patterns, and integration points.

Stage 3

Challenge — Senior PM

Your Senior PM reviews the draft for gaps, feasibility, and completeness — and sends it back where it falls short.

Stage 4

Revise — writer / reviewer loop

Your PM and Senior PM iterate back and forth, tightening the spec until the bar is met. Each round closes gaps the previous one missed.

Stage 5 · Gate

Human review — you

You review the PRD across as many rounds as it takes. Request changes with context, or move it forward.

Stage 6 · Gate

Approved PRD — ready to build

The approved PRD feeds directly into the App Build pipeline. The spec your Build Team starts from is tight.

Your PM writes. Your Senior PM challenges. You decide. A PRD nobody argued with is a PRD nobody checked.

What your team produces

Inside a Fostery PRD.

Not a prompt dump. A structured document your Build Team can execute against — and you can hand to a contractor next year without explaining anything.

Executive summary

What gets built — and what doesn't touch your codebase.

Scope is locked before any code is written. What's in, what's out, what this feature is for. No scope creep. No "I thought we were also doing X." The boundaries are written down and you approved them.

SCOPE: password reset for verified-email users
OUT-OF-SCOPE: SMS, admin overrides
PARENT URD: UR-AUTH-RECOVERY v3
Goals & metrics

You know exactly when this feature is done.

Measurable targets with baselines. Anti-goals that tell the team what not to build. No more arguing about whether the feature is "ready" or gold-plating something that was supposed to ship last week.

G-001: 95% self-serve recovery
METRIC: time-to-recovery, 8h → < 2 min
ANTI-GOAL: no new SMS dependency
Functional requirements

No more "that's not what I meant" three days later.

Every requirement is numbered, testable, and carries acceptance criteria attached directly to it. When your Build Team picks up this spec, there is nothing to interpret. It either passes or it doesn't.

PRD-FUN-001 (M): user MUST receive reset link
AC-001.1: GIVEN valid email WHEN reset
requested THEN link sent within 5s
Domain inventory

Your team won't reinvent what already works.

An inventory of what already exists in your codebase — each with a disposition: extend it, replace it, or leave it alone. Your Build Team reuses your patterns instead of creating parallel implementations you'll spend a week untangling.

EXISTING: mailer at lib/mailer.ts (Extend)
EXISTING: session — JWT (Stay-Clear)
ALREADY-SATISFIED: UR-AUTH-003
Correction log

You can see exactly where the spec got tighter.

Every round of your Senior PM's review is recorded — what was challenged, what was fixed, what was deferred. You're not blindly trusting AI output. You can read the argument that made the spec better.

ROUND 1: 4 issues — 4 addressed
ROUND 2: 2 issues — enumeration edge added
ROUND 3: 0 issues — approved
Before / after

Two lines in. A buildable spec out.

You bring the intent. Your Product Team brings the structure, the edge cases, and the code-awareness.

Feature spec

Goals, scope, success criteria

What this is, who it's for, what bounds it, and how you'll know it works.

Required behaviours

What the system must do

The rules and behaviours in plain English — what users can do, what the system must guarantee. The Build Team decomposes these into stories; the PRD stays at the WHAT.

Edge cases

The cases you didn't mention

Unknown inputs, expired states, repeated requests, failure modes — surfaced and named before any story is written.

Code-aware constraints

Grounded in your architecture

References to your real services, existing patterns, and integration points — so the build reuses, not reinvents.

Other workflows

What else your team does.
